The 2014 Lexus IS sedan has been turning heads and dividing public opinion since we first drove it. Then, as now, we knew that a revamped IS F would be in the offing at some point, but until today we had know idea what form the Lexus would take.

Our first ever batch of 2015 Lexus IS F spy shots has just come across the transom, and the camouflaged coupe – that's right, there are just two doors this time out – is awfully intriguing at first glance. A much more aggressive front end is prominent, as is the slinky roofline that finishes in a pert rear end. The signature IS grille is still in effect here, at least in terms of the shape, and while the headlamps are covered up, we'd expect some variation of the slash-like units on the 2014 IS.

Hinting at the car's performance intentions are large slotted brake rotors with significantly sized calipers, all tucked in behind dark-finish wheels. Quad exhaust tips and a retractable spoiler can be seen at the back of the car.

Unfortunately, we still don't know what to expect in terms of engine – there's some evidence that the current car's 5.0-liter V8 won't meet European emissions standards. A turbocharged V6 of some kind would certainly match up with the reported mills in the upcoming BMW M4, however, and the hood scoop seen above lends some credence to that thought process. In any case we'd expect north of 450 horsepower in terms of output.

There's no question that the prototype pictured in these fresh spy shots is the all-new Lexus IS-based Coupe, but how can one be sure that it's the on-and-off (up until now, that is), F-badged high-performance version and not the simpler F-Sport variant?

Glad you asked, because the answer is right in front of our eyes. Despite the liberal use of camouflage wrap on the body, if not all, most telltale signs that this is indeed the IS-F Coupe are here starting with the stacked twin tailpipes on either side of the diffuser along with what looks to be a retractable spoiler.

Do want more evidence? No problem. Let's go around to the front where we find a slotted bonnet along with a caged "spindle" grille and huge corner air intakes. Finally, we take a look at the car's profile and the blistered front and rear wheel arches, the vented front fenders, sculptured side skirts and low profile tires through which we can see the massive brake calipers and discs.

What we cannot see from these spy shots of the very first IS F Coupe in the history of the series is what kind of performance lump is hiding under the hood – at least for the time being. Lexus officials have hinted in the past that the previous IS F's 416hp 5.0-liter naturally aspirated V8 wouldn't be used in future models because it doesn't meet Euro 6 emissions standards.

That said, we can only speculate about what Lexus is preparing – it could be a newer V8, a force-fed V6 or perhaps even a combination of one of the previously mentioned lumps with an electric motor, which would make sense for a company priding itself on planet-friendly hybrid technology. Whatever Lexus chooses, it will deliver somewhere around 450-horses to compete against the BMW M4, linked to an automatic or dual-clutch transmission driving the rear wheels.

We also don't know for sure if Lexus will name the two-door model the IS Coupe or if it will use another moniker (even though it is based on the IS sedan) following the example of one of its chief competitors, BMW and its 4-Series. For the record, the concept that previewed the IS-based Coupe was named LF CC.

Read what I'm saying. I've pointed out that it's gonna be a hideous car. Doesn't matter that you have an IS now, it's not hard on the eyes. I don't want to see that in your sig all the time. It's hard enough looking at cBass' car all the time.
